Design And Application Of Wind Turbine Tower

Qingdao Wuxiao | Updated: Sep 05, 2017

     As the wind turbine construction costs, transportation costs and installation costs continue to rise, and the limitations of the wind turbine tower 80 meters limit the potential of large fans, developers are trying to develop a higher and more effective new tower. The use of higher towers by wind turbines will effectively improve power production. If the current 2 to 3MW wind turbines with 80m high tower, can be compared to the use of 60m tower fan has greater power production capacity, on the other hand, the higher tower can also enable large-scale wind turbines into the market. At the same time, the high tower frame makes the fan blades in the steady airflow, which reduces the fatigue and wear of the fan.Wind Turbine Tower

    Of course, building higher towers means increasing costs, and manufacturers have to carefully consider whether the cost of developing new towers is reasonable, and that the associated investment and increased costs need to be recovered within the first 5-8 years of the operation of the blower.Wind Turbine Tower

    Thus, the thinner tower material can be used to improve the steel usage, thus reducing the cost and weight. A new type of tower mounting flange is used with the same standard as the conventional tower, and the flange at the top and bottom of the tower can be connected with the fan and the base by conventional interface. The increased diameter of the bottom of the tower makes the foundation area wider, while the whole foundation does not have to be dug deeply, which reduces the expensive buried seal ring in the traditional Tower Foundation.Wind Turbine Tower

    Modular towers need to be assembled before they are erected. The use of friction-type connection methods used in the construction of bridges and high-rise buildings is carried out on-site erection of towers. The structure of the tower slab and the connection method of the friction bolt are used to make the assembly welding process only 10% to 15% of the traditional tower installation. In addition to further reducing manufacturing time and cost, another advantage of adopting a frictional connection is that the Tensioning tool does not have to be calibrated to reduce the risk of errors during installation because the tensioning process is not achieved through torque.Wind Turbine Tower
